Wyoming Fuel is concerned <br />that the cause of death be rapidly determined, and that appropriate steps <br />be taken to preclude reoccurrence of the problem. The purpose of this <br />letter is to share with you what information we have at this time about the <br />possible cause of this problem and outline what we are doing with respect <br />to the problem. <br />Our discharge permits place certain limitations upon the level of <br />suspended solids which we can discharge into the Purgatoire River. In <br />order to keep the level of suspended solids within permissible limits, we <br />initiated, several months ago, the use of coagulants or flocculants in our <br />settling ponds in order to settle out the solids. More recently, we have <br />been utilizing a product called Nalco 8852 Coagulant. <br />We have enclosed, for your information, a copy of the Material Safety <br />Data Sheet (MSDS) regarding the coagulant. The MSDS notes that the product <br />is approved for use as a coagulation aid in the treatment of potable water, <br />and that it does not constitute a hazardous substance under the variety of <br />regulations listed on pages 5 and 6 of the MSDS. However, page 4 of the <br />MSDS notes that the product is toxic to fish, such as trout, and that it <br />should not be directly discharged into lakes, ponds, streams, waterways or <br />public water supplies. It is our understanding that the product may affect <br />the gill system of fish. <br />
